Abstract
A spyhole viewer, mountable in a wall surface is disclosed and provides a wide angle view, while requiring a small diameter mounting hole. An objective lens system produces a real inverted image, a reflector angularly deflects light from the objective lens system, and an erector, located behind an element of objective lens system, erect the image. Further, a image surface upon which the image will appear, and a projection viewing lens are provided. The image optical axis is angularly deflected at least once between the objective and viewing lens systems.
